the use of biogenic selenium nanoparticles for various purposes is going to be an issue of considerable importance; thus, appropriate simple methods should be developed and tested for the synthesis and recovery of these nanoparticles. in this study, a fungus was isolated from a soil sample, identified as aspergillus terreus and used for extracellular synthesis of selenium nanoparticles (se nps)...

A new form of governing equations is derived from Hamilton’s principle of least action for a constrained Lagrangian, depending on conserved quantities and their derivatives with respect to the time-space. This form yields conservation laws both for non-dispersive case (Lagrangian depends only on conserved quantities) and dispersive case (Lagrangian depends also on their derivatives). For non-di...

Dispersive soils are exemplary that in the presence of water they exhibit highly erosive behaviour. Stabilization dispersive through Xanthan Gum (XG) biopolymer is a sustainable, efficient, and long-term alternative to traditional techniques. The present study aims evaluate strength durability performance treated subjected different adverse environments. An unconfined compressive (UCS) specimen...

The HYDRUS-1D and HYDRUS (2D/3D) computer software packages are widely used finite element models for simulating the one-, and twoor three-dimensional movement of water, heat, and multiple solutes in variably-saturated media, respectively. While the standard HYDRUS models consider only the fate and transport of individual solutes or solutes subject to first-order degradation reactions, several ...
